Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims priority from European Patent
Application No. 17205263.1 filed Dec. 4, 2017, the contents of
which are hereby incorporated by reference into this
application.
FIELD OF THE INVENTION
[0002] This invention relates to the field of heat distribution
management mechanisms in heat treatment devices for wires and more
specifically to the field of mechanisms for the optimization of
heat distribution around the portion of wire to be treated on the
inside of a heat treatment device.
BACKGROUND OF THE INVENTION
[0003] At present, the treatment of a wire or of a wire bundle in a
treatment device takes place through the placement of the wire on
the conveyor belt which moves inside the treatment device.
[0004] On the inside of the treatment device, the wire or wire
bundle may be guided to switch means of transport passing from one
belt to another depending on the defined path.
[0005] In the framework of heat treating, for example, by
distribution of steam flows in a treatment chamber, the means of
transport are realized in the form of a structure or transport
device which allows a traversing by steam flows and/or by heat
flows. This construction of the means of transport thereby
participates in the heat treatment on each of the faces of the wire
bundle placed on the means of transport. Thus, the heat treatment
is not exclusively accomplished on the sole exposed face of the
wire on the means of transport, which is to say to the detriment of
the wire face which would be in direct contact with the means of
transport.
[0006] Nonetheless, this particular structure of the means of
transport presents a disadvantage in the treatment of the ends of
the wire or of the wire bundle.
[0007] Indeed, during the placement of the downstream wire end, the
surface of the means of transport is free on at least one part of
its length up until the wire or wire bundle is placed on the whole
of the length of the means of transport. Furthermore, when only a
part of the length of the means of transport is covered by the wire
or wire bundle, the part of the free means of transport then
presents a structure which more readily enables the flows of heat
and steam than the part of the means of transport which is covered
by the wire or wire bundle. The flows of heat or of steam then have
the tendency to firstly travel through the part of the means of
transport which presents a free structure. Such a priority of
placement is made to the detriment of the part of the means of
transport which carries the wire or wire bundle and therefore to
the detriment of the quality of the heat treatment of the
wires.
[0008] There is the identical problem at the upstream end of the
treated wire or wire bundle. This problem of heat distribution in
the heat treatment device therefore leads to the production of a
wire or wire bundle having a heterogeneous quality of treatment
over its whole length.
BRIEF SUMMARY OF THE INVENTION
[0009] This invention intends to overcome these disadvantages by
proposing a solution which, on the one hand, allows for a wire or
wire bundle having an identical treatment over the whole of its
length and which, on the other hand, can readily be implemented in
an already existing heat treatment device.
[0010] The subject matter of the invention is therefore a heat
distribution management device in a treatment device of wires in
movement on a means of transport, the means of transport being able
to be traversed by a flow of heat at or through the orifices,
characterized in that the device comprises at least one means of
sealing or sealing device by coverage of at least one part of the
orifices of the means of transport, this means of sealing being
independent of the means of transport.
[0011] The invention furthermore relates to implementation process
of at least one heat distribution management device according to
the invention, characterized in that the process comprises: [0012]
a stage involving placement of the heat distribution management
device on a means of transport at the inlet opening of the
treatment device of the wires, [0013] a stage involving
distribution of the management device on at least one part of the
width of the means of transport.
[0014] The invention furthermore relates to a mechanism for the
recovery of a heat distribution management device according to the
invention, characterized in that said recovery mechanism, capable
of being positioned at the outlet of the treatment device of the
wires, comprises at least: [0015] one fastening interface to at
least one end of the management device, [0016] one pivot axis which
the fastening interface is mounted on, [0017] one device for
coiling around the pivot axis, [0018] one device for adjustment of
the coiling speed on the basis of the speed of movement of at least
one means of transport of the treatment device of the wires.

DETAILED DESCRIPTION
[0023] In this document, the terms "downstream" and "upstream"
define positions in relation to the direction of movement of a wire
being treated and/or of a wire on a means of transport 1 of the
treatment device 5.
[0024] This invention relates to a heat distribution management
device in a treatment device 5 of wires 6 in movement on a means of
transport 1, said means of transport 1 being able to be traversed
by a flow of heat at or through the orifices, characterized in that
the device comprises at least one means of sealing 2 by coverage of
at least one part of the orifices of the means of transport 1, this
means of sealing 2 being independent of the means of transport.
[0025] The means of sealing 2 of the device is intended to take the
place of a wire or a wire bundle 6, upstream and/or downstream of
the wire or wire bundle 6 that is to be treated, during the
treatment of the wire 6 placed on the means of transport 1 in the
treatment device 5 of the wires 6. This means of sealing 2 thereby
allows the coverage of the orifices of the means of transport 1 in
a manner similar to that of an equivalent wire or wire bundle 5
which would be positioned upstream or downstream of the wire or
wire bundle 5 to be treated. Furthermore, the movement of the flows
of heat or of steam through the part of the means of transport 1
which does not carry the wire or the wire bundle 6 is limited, or
even precluded, in the same manner as if the part of the means of
transport 1 was carrying a wire or wire bundle 6.
[0026] As a consequence, the distribution of the flows of heat or
of steam is homogenized over the whole of the wire 6 part that is
undergoing treatment on the means of transport 1 in the heat
treatment device 5.
[0027] According to an embodiment feature of the management device
of the invention, the means of sealing 2 is realized in the form of
a fabric belt or of a wire bundle. The choice of the means of
sealing 2 is taken on the basis of the type of wire or of wire
bundles 6 treated upstream and/or downstream of the means of
sealing 2. Furthermore, on top of the width of the distribution of
the placement of the wire or of the wire bundles 6 on the means of
transport 1, that are to be considered to select the means of
sealing 2, it is likewise important to consider the propensity of
the treated wire or wire bundles 6 to be traversed by a flow of
heat or of steam.
[0028] Thus, the means of sealing 2 is selected on the basis of the
sealing or to the contrary permeable nature of the treated wire or
wire bundles 6 for the passage of a flow of heat or of steam in
order to optimize the homogeneity of the distribution of the flows
in the treatment device 5 of the wires 6.
[0029] According to a construction feature, the heat distribution
management device is characterized in that the length of the device
is adapted to be at least equal to the cumulative length of the
whole of the means 1 participating in the transport of wires 6 in
the treatment device 5 of the wires 6. This construction feature
allows for a device, according to the invention, of which the means
of sealing 2 is sufficiently long to seal the whole of the means of
transport 1 of wires in the treatment device 5, before and/or after
the treatment of the wire or of the wire bundle 6.
[0030] According to a construction feature that is complementary
and/or alternative to the preceding construction feature, the heat
distribution management device is characterized in that the length
of the device is adapted to be at least equal to the length
traveled by a wire 6 in the treatment device 5 of the wires 6. This
construction feature allows for a device according to the invention
the length of which is best adapted to the path followed by the
wire or wire bundle 6 in the treatment device 5. Indeed, in
particular when the wire 6 is caused to be transferred from one
means of transport 1 to another, it can occur that the length of
the path followed by the wire 6 is different from the cumulative
length of the means of transport 1. Thus, when the wire or wire
bundle 6 does not move over the whole of the length of the means of
transport 1, the length of the path of the wire 6 is shorter than
that of the cumulative length of the means of transport 1.
Conversely, when the wire or wire bundle 6 is transferred from one
means of transport 1 to another by means of a drop between the two
means of transport 1, the length of the fall increases the path of
the wire or wire bundle 6 in relation to the distance of movement
undertaken on the sole means of transport 1.
[0031] According to another construction feature of the device of
the invention, the width of the device substantially corresponds to
the width of the whole of the wires 6 to be treated by the
treatment device 5. In a complementary manner, the width of the
device corresponds to the width of the spread of the wire bundle 6
on the surface of the means of transport 1.
[0032] According to another construction feature of the device of
the invention, the device comprises at least one fastener of the
means of sealing 2 to one end of a wire or of one wire bundle 6.
This fastener is preferably associated with the means of sealing 2
at its end. Thus, the fastener maintains the fastening of the wire
or wire bundle 6 with the means of sealing 2 over the whole of the
path of treatment in the heat treatment device. The risks of
discontinuity between the wire or wire bundle 6 and the means of
sealing 2 are reduced and the quality of the distribution of the
heat and/or steam flows in the heat treatment device 5 is
maintained.
[0033] The invention moreover relates to an implementation process
of at least one heat distribution management device according to
the invention, characterized in that the process comprises: [0034]
a stage involving placement of the heat distribution management
device on a means of transport 1 at the inlet opening of the
treatment device 5 of the wires 6, [0035] a stage involving
distribution of the management device on at least one part of the
width of the means of transport 1.
[0036] According to an implementation feature, the process
according to the invention is characterized in that it comprises:
[0037] a stage involving movement of the heat distribution
management device on a means of transport 1 and a subsequent
driving of a least one wire 6 to be treated, [0038] a stage
involving occupation by the heat distribution management device and
at least one wire 6 to be treated, of the length of the whole of
the path of the wire 6 to be treated on the means of transport 1 of
the treatment device 5 of the wires 6.
[0039] According to an alternative implementation feature, the
process according to the invention is characterized in that it
comprises: [0040] a stage involving movement of the heat
distribution management device on a means of transport 1 being
subsequently driven by at least one wire 6 to be treated, [0041] a
stage involving occupation by the heat distribution management
device and at least one wire 6 to be treated, of the length of the
whole of the path of the wire 6 to be treated on the means of
transport 1 of the treatment device 5 of the wires 6.
[0042] The invention furthermore relates to a mechanism for the
recovery of a heat distribution management device according to the
invention, characterized in that the recovery mechanism, which is
able to be positioned at the outlet of the treatment device 5 of
the wires 6, comprises at least: [0043] one fastening interface to
at least one end of the management device, [0044] one pivot axis 3
upon which the fastening interface is mounted, [0045] one device
for coiling 4 around the pivot axis 3, [0046] one device for
adjustment of the coiling speed on the basis of the speed of
movement of at least one means of transport 1 of the treatment
device 5 of the wires 6.
[0047] According to a construction feature of the recovery
mechanism, the fastening interface is arranged to interact with an
end of the means of sealing 2 of the management device.
[0048] According to another construction feature of the mechanism,
the adjustment of the coiling speed is carried out on the basis of
the speed of movement of the last means of transport 1 which
carries the management device of the invention.
[0049] Let it be clear that the invention is not limited to the
embodiment described and represented in the appended drawings.
Modifications remain possible, in particular, from the point of
view of the make-up of the various elements or through substitution
of equivalent techniques without however leaving the scope of
protection of the invention.
